FRANK F. ROWELL, OF SCRANTON, PENNSYLVANIA.

URINAL-SLAB.

To all whom it may concern:

Be it known that I, FRANK F. ROWELL, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Urinal-Slabs, of which the following is a specilication.

My invention relates to urinals and particularly to a floor slab therefor adapted to be used either alone as a urinal or in conjunction with a back slab or with any other type of urinal.

In urinals as ordinarily constructed, the urinary droppings fall upon the Hoor beneath the urinal and thus a Very unsanitary condition arises.

Urinals have been constructed in which a floor slab is to be used, but in thesethe floor slab is made with an unbroken upper surface which is uniiushed and therefore is in many ways as bad from a sanitary point of view as a urinal without any floor slab would be.

In order to avoid the above recited objections, I have provided a floor slab consisting of a body of china, porcelain, cement,

' or other suitable material, the upper sur-` face of which at its forward endV 1s formed with aseries of ribs or corrugations upon Awhich the user stands. The rear of the slab is slinken and provided with an outlet, and

in conjunction with the series of ribs I provide means for flushing the grooves between the ribs. In conjunction with a floor slab as above constructed, I may also provide a Ventilating hood located near the floor of the slab but at its rear end and adapted to carry olf all foul odors. Further, the floor slab is so constructed that it may be applied in connection with a back slab having the usual flushing arrangements.

Referring to the drawings: Figure l is a perspective View of my improved floor slab used in conjunction with a back slab. Fig. 2 is a longitudinal vertical section of Fig. l. Fig. 3 is a plan view of a modified form of floor slab. Fig. 4L is a longitudinal vertical section on the line 4?-4. Fig. 5 isr a fragmentary transverse section on the line 5 5 of Fig. 3.

My slab consists of a base 2, which may be made of vitreous china, glazed or unglazed, porcelain, lire-clay, cement, 0r any suitable or desirable material. At its rear the slab is provided with an upwardly extending Specification of Letters Patent.

flange 3, the upper edge of this flange being rabbeted, as atI 4, to form a joint with the back slab. The rear is also provided with the forwardly projecting side flanges 3a, which are also rabbeted to form a joint with the side flanges of a back slab. Both sides of the slab are provided with the marginal upwardly extending flanges 5. The upper surface of Athe slab is inclined vdownwardly from front to rear so as to drain toward the' rear of the slab. l The front wall 7 is tubuany other means for carrying off the liquidA material at the lowest level of the slab.

The tubular bore S has a series of holes ll opening into spaces between the ribs 9. This tubular bore is adapted to be connected to any sourceof water supply and to this end may be provided with an internal tubular lining 11a provided with holes which will aline with the holes in the wall 7, this Abeing connected to a water supply pipe.

Vhile, the floor slab as above described mayV be used by itself as a urinal, I may also provide in conjunction therewith, the back slab 12 having the side walls 13. The side walls and back slab are rabbeted, as before referred to, having engagement with the rabbet-ed flanges of the base. The upper end of the back slab is provided with any suitable constant or intermittent flushing device whereby streams of water,` may be directed down the face of the back slab and drained off through the outlet 10 of thel floor slab. 14 designates a water inlet pipe for this purpose and 15 'a tubular header by which the water is directed along the face of the slab, this header being perforated. The

bore 8 may also vbe connected to any constant ror intermittent source of water supply so that the floor slab may be flushed inter# mittently or continuously.

Preferably, the ioor slab at its rear end is provided with a hood 1G which is formed @will drip immediately into the drainagerecess 17 which surrounds the: outlet pipe.

The back flange S'isperforated asfat 18 and connected with any suitable vent Vpipe yor Aother outlet forfoulodors.V While I have shown. the hood assemicircular in plan, I do notwishto" be limitedto thisy specialform.

- fio It is designed that this-floor slab-may be used in vconjunction with any type of water flushing urinal desired, but, as before stated,

the slabmay Ybe used byfitself vas a urinal or Y anulnber of these slabs may be placedV together to'make?acontinuousurinal of any extent desired. Y Y i The advantages of my invention reside in the'fact'that a floor space is providedhaving aVV minimum of tread'surface, thus permating theurinarydroppngs t0 .be fmed forwardy and f drained.' into the outlet pipe and'.,'preirentingzthe faceY offthe slab fromj remaining in any. wet condition. Further Vthan this, my `construction permitsv of Hushing beneath the feet of theusers, thus cleansing points of contact, neutralizingthe Vuric acids,and eliminating all odors arising from urinary droppings. Further'thanthis, my construction' 'provides `a sanitary Vfloor vbase i Y Vforthe ordinary'V form ofback slabs, which maybe used either by itself or inY conjunction with any -form of backfslab, andwhich `being 'a un`it ,rmay be conjoined'with other likeunits to form a urinal of any desiredY 1 length. In addition ,to these advantages,

` n erated.r

'i VVthe Ventilating hood carries olf foul odorsat the: pointj -wherethey are particularly gen- Myjlinvention .is simple, sanitary, easily .Y made, and'has been found extremely effective in practice.

' Having thus described Vthe invention, what I claim as new is:

' l. A urinal floor slab` consisting of abase having atone end a drainage opening, and

Y "having its upper surface inclined toward the vdrainagejopening, said upper surface having' la seriesofY ribs `direct-ed toward the fdrainagefopening and forming a tread sur-V .Y face,the,higher end of the slab being proi `vided with a waterchamberradapted to be connected to a source ofwater supply, said chamber 'having perforations leading therefromptor-the. spaces between the ribs, said ribs having a rounded upper edge. e f2. A iioor slab for urinals comprising a base having a rearwardly and downwardly inclined upper surface, a transverse gutter at therear ofthe base inclined toward the middle of the rear of the-base,- the slab beingprovided at this point with a drainyage opening, saiduppersurface of the slab havin kthereon a series of ribs directed towar the said gutter and drainage opening 'and forming a tread surface, the up er edgesof the ribs being rounded, the hig ier Yend of the-"slab being provided with a water chamber extending across the endsof all the ribs and connected to a source of water su ply, said chamber having perforations lealding therefrom to the spaces between the ribs.

f3. A floor slab` for urinals comprising a base having an upv-standing marginal flange, the -rear flange of the basealiaving a rounded insideface, said base having inside of said flange :a rearwardly and downwardly in` clined upper surface provided at its lowest point'with a drainage opening, the face of the Vbase being'formed ywith a series of ribs extending directly'` toward the lowest portion ofthe base, said Vribs being rounded upon their upper edges, the end flange of the base'opposed to the drainage opening being tubular and provided 'with means whereby it `may be connected to a source of water and being further provided with perforationsalining with lthe spaces between the ribs and adapted to direct flushing water into the spaces between the ribs. 4f, A combined urinal stall and floor having an inlet `pipe and a series of small outlet nozzles formed inl theA back of the stall and arranged to flush the back and sides of the stall and Aanother pipe opening upon the floor and vhaving a series of small nozzles arranged to. thoroughly flush the floor, said floor being inclined downward and rearward vand there provided with a drainage outlet, said floor being further provided with a' series of rearwardly extending up fwardlyV projecting ribs forming a tread surface, said ribs being rounded upon their upper edges. i

5. VIn a urinal, a i'earwall and a floor said 'floor being rearwardly inclined and provided with a" drainage outlet, the rear wall having al flushing inlet and the front end ofthe floor being also' provided with af flushing inlet, said floor being formed with a series of integrant ribs forming ay tread surface and extending across' the rear wall. In testimony whereof I affix my signature in presence of two witnesses.
